Product catalog summary

Introduction to PressPro
PressPro is a series of standardized, compact press control blocks designed for hydraulic press applications. These blocks utilize conventional directional control valves and slip-in cartridge valves, available in sizes ranging from 6 to 63. For sizes up to 32, conventional directional control valves are used, while larger sizes employ slip-in cartridge valves. PressPro is developed for forming applications in compliance with DIN EN 693:2011-11, ensuring general safety requirements are met for hydraulic presses.

What is PressPro? PressPro are standardized, compact press control blocks for hydraulic press applications, which are realized with conventional directional control valves as well as slip-in cartridge valves. Eaton provides these blocks in the range from size 6 up to 63. Up to size 32 these blocks are realized with conventional directional control valves. Larger blocks are based on the Slip-in cartridge valve principle. The press control PressPro are developed for forming applications according to DIN EN 693:2011-11. To fulfill and achieve the general safety requirements PressPro control blocks...

The following circuits represent two examples of the PressPro control. Up to size 32 conventional 4-3 directional valves are implemented for the directional function. For higher flow slip-in cartridge valves fulfill that function. For all PressPro control blocks the safety concept is identical, but can be extended by secondary functions depending on the specific application. Example: PressPro up to size 32 (directional valve) Example: PressPro up to size 63 (cartridge valves) EATON PressPro technical information brochure E-VLOV-BB001-E May 2017
